# json-stringify-safe
Like JSON.stringify, but doesn't throw on circular references.
## Usage
Takes the same arguments as `JSON.stringify`.
```javascript
var stringify = require('json-stringify-safe');
var circularObj = {};
circularObj.circularRef = circularObj;
circularObj.list = [ circularObj, circularObj ];
console.log(stringify(circularObj, null, 2));
```
Output:
```json
{
"circularRef": "[Circular]",
"list": [
"[Circular]",
"[Circular]"
]
}
```
## Details
```
stringify(obj, serializer, indent, decycler)
```
The first three arguments are the same as to JSON.stringify. The last
is an argument that's only used when the object has been seen already.
The default `decycler` function returns the string `'[Circular]'`.
If, for example, you pass in `function(k,v){}` (return nothing) then it
will prune cycles. If you pass in `function(k,v){ return {foo: 'bar'}}`,
then cyclical objects will always be represented as `{"foo":"bar"}` in
the result.
```
stringify.getSerialize(serializer, decycler)
```
Returns a serializer that can be used elsewhere. This is the actual
function that's passed to JSON.stringify.
**Note** that the function returned from `getSerialize` is stateful for now, so
do **not** use it more than once.
